the CKP can be hard to seat in the engine properly if not in the exact position it will not run correctly . try to place into this exactly as it was..... disconnect the negative to the battery to make the PCM start from the factory set points . if not fixing it , then may need to be programmed by a GM dealership with the proper diagnostic programmer tool. forgot PUT THE OLD ckp BACK IN !!!!!!!
